Answer:

El área original del cuadrado es de 1825 centímetros cuadrados.

Step-by-step explanation:

De acuerdo con el enunciado, tenemos que el área del cuadrilátero es:

[tex](15\cdot n +9\cdot n\cdot x)\,cm^{2} = (3\cdot n\,cm)\cdot h[/tex] (1)

Donde [tex]h[/tex] es la altura del cuadrilátero, medida en centímetros.

De ahí sacamos que la altura es igual a:

[tex]h = (15+9\cdot x)\,cm[/tex]

También se sabe que el cuadrado con la misma altura del cuadrilátero menos un área determinada es igual a lo siguiente:

[tex](h^{2}-9\cdot x^{2})\,cm^{2} = 1825\,cm^{2}[/tex]

[tex][(15+9\cdot x)^{2}-9\cdot x^{2}]\,cm^{2} = 1825\,cm^{2}[/tex]

[tex]225+270\cdot x+81\cdot x^{2}-9\cdot x^{2} = 1825[/tex]

[tex]72\cdot x^{2}+270\cdot x +225 = 1825[/tex]

[tex]72\cdot x^{2}+270\cdot x -1600 = 0[/tex] (2)

Esta es una ecuación cuadrática, el cual puede ser resuelto por la Fórmula de la Cuadrática, cuyas soluciones son, respectivamente:

[tex]x_{1} \approx 3.198[/tex] y [tex]x_{2}\approx -6.948[/tex]

Sabemos que las longitudes son variables positivas, por tanto, solo se debe escoger aquellas soluciones de [tex]x[/tex] que cumplan tal condición. Empleamos la altura del cuadrilátero para la evaluación:

[tex]x_{1} \approx 3.198[/tex]

[tex]h_{1} = 15+9\cdot (3.198)[/tex]

[tex]h_{1}\approx 43.782\,cm[/tex]

[tex]x_{2}\approx -6.948[/tex]

[tex]h_{2} = 15+9\cdot (-6.948)[/tex]

[tex]h_{2}\approx -47.532\,cm[/tex]

Entonces, el valor apropiado de [tex]x[/tex] es aproximadamente 3.198.

Por último el área original del cuadrado es:

[tex]A = (43.782\,cm)^{2}[/tex]

[tex]A = 1916.864\,cm^{2}[/tex]

El área original del cuadrado es de 1825 centímetros cuadrados.

Answer:

the GCF is [tex]5c^2[/tex]

Step-by-step explanation:

The Greatest Common Factor (GCF)

The highest number that divides exactly into two or more numbers.

To find the GCF of monomials quantities, we find their prime factors and multiply the common factors with the lowest exponent:

We are required to find the GCF of the polynomial:

[tex]10c^3-80c^6+5c^2[/tex]

Factor the monomials:

[tex]10c^3=2*5*c^3[/tex]

[tex]80c^6=2*2*2*2*5*c^6[/tex]

[tex]5c^2=5*c^2[/tex]

Take the only common factor 5 and c to the lowest power [tex]c^2[/tex]

Thus, the GCF is [tex]5c^2[/tex]

And the expression is factored as:

[tex]5c^2(2c-16c^4+1)[/tex]

Answer:

the answer is B if wrong sorry

Step-by-step explanation:

62+82=122

No, this triangle is not a right angled triangle because 12²≠6²+8² .

The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Formula of Pythagoras theorem:

[tex]Hypotenuse ^{2} = Perpendicular^{2} +Base^{2}[/tex]

According to the question

The side lengths of a triangle : 6 , 8 , 12

Now according to  Pythagoras theorem

If it is a right angled triangle then its sides should follow Pythagoras theorem  

i.e

[tex]Hypotenuse ^{2} = Perpendicular^{2} +Base^{2}[/tex]

[tex]12 ^{2} = 8^{2} + 6^{2}[/tex]

but

144 ≠ 64 + 36

144 ≠ 100

Therefore, it is not a right angled triangle .

Hence, This side lengths of a triangle is not a  right angle triangle because 12²≠6²+8² .

The amount in compound interest is greater than the amount in simple interest for 2 years

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Maya will deposit $1,650 in an account that earns 5% simple interest every year.

So , SI = 1650 x 4 x 5 / 100

SI = $ 330

So , the total amount A₁ = 1650 + 330

A₁ = $ 1,980

Let the compound interest amount be represented as A

Now , the interest rate r = 5 %

The number of times the interest is applied = annually

The principal amount P = $ 1,600

CI = 1600 (1 + 8/100/1)⁴ - 1600

CI = $ 853.68

A₂ = 1600 + 853.68

A₂ = $ 2,453.68

Hence , the amount in CI is greater

Answer:

B

Step-by-step explanation:

y=(x+4)2+3

Answer:

86 miles.

Step-by-step explanation:

Assuming they rented the car for one day, we'll subtract the $20 fee.

41.50-21= 21.50

Since it's $0.25 per mile, we then divide by .25

21.50/0.25 = 86

This means they travelled 86 miles.

Answer:

12709 balls

Step-by-step explanation:

Given

Dimension of Room = 15 ft by 20 ft by 10 ft

Diameter of Ball = 9.2 inches

Required

Determine the number of balls that can be occupied by the room

First, we need to calculate the volume of the room

This is done by multiplying the dimensions of the room

[tex]Volume = 15ft * 20ft * 10ft[/tex]

[tex]Volume = 3000ft^3[/tex]

Next, we calculate the volume of the ball.

The ball is a sphere.

So:

[tex]Volume = \frac{4}{3}\pi r^3[/tex]

Where

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * 9.2[/tex]

[tex]r = 4.6\ in[/tex]

So:

[tex]Volume = \frac{4}{3}\ * \frac{22}{7} * (4.6in)^3[/tex]

[tex]Volume = 407.88419\ in^3[/tex]

To calculate the number of balls, we then divide the volume of the room by volume of a ball

[tex]Balls = \frac{3000\ ft^3}{407.88419\ in^3}[/tex]

Convert ft^3 to in^3

[tex]Balls = \frac{3000 * 1728in^3}{407.88419\ in^3}[/tex]

[tex]Balls = \frac{3000 * 1728}{407.88419}[/tex]

[tex]Balls = \frac{5184000}{407.88419}[/tex]

[tex]Balls = 12709.4899167[/tex]

[tex]Balls = 12709[/tex] -- approximated

Hence, the room will contain 12709 balls
